How can I load class nelmiocorsbundle in symfony 4.2

Question

I have installed NelmioCorsBundle with composer require nelmio/cors-bundle but when i send a request i have the below error:

Attempted to load class "NelmioCorsBundle" from namespace "App\Nelmio\CorsBundle"

Did you forget a "use" statement for "Nelmio\CorsBundle\NelmioCorsBundle"?
